Hi! I have been searching the internet for some places to buy footie pajamas. Up until this point I hadn't found many online stores with fabric patterns I like. I haven't seen this store mentioned anywhere so I thought I'd put it out there and share the love:
Spencer's Gifts, a kooky adult gift shop, has a few different childish designs of adult footie pajamas. They've got ones with Spongebob, Angry Birds, Strawberry Shortcake, Minnie Mouse, Gonzo, Elmo, Kermit the Frog,...and the list goes on. They also have awesome character plushie slippers.
PLEASE NOTE: Some of the pjs are one piece but have no footies, but also...One really bad side to these is they're mostly in the women's clothing section and their X-Large size will fit someone only up to 5'8" and 150 lbs. So sorry to everyone that's bigger! I just looked at the sizes and saw how mean they were... but for short/small people like me they're awesome. Anyway, happy shopping. If you google the shop name it should pop right up.
